From a foundational point of view, it would be relevant to explore whether the relation between contextuality and cloning fidelity,
that we proved for optimal state-dependent cloning, extends to the other types of imperfect cloning studied in the literature, mainly phase-covariant and/or universal cloning, as well as to probabilistic cloning [1]}. From an applications' point of view, one important open question is if our noncontextual bound can be used to prove a contextual advantage for quantum information processing tasks which rely on optimal quantum state-dependent cloning (e.g., [2]}, [3]}).
